In this part of the Learn to Program series we make a working calculator from start to finish in one video. We create a Use Case Description to figure out exactly what must occur in the program step-by-step. We then create a calculator object, convert the use case into code, create the GUI interface using TkInter and end with homework you should solve to improve your programming abilities. Calculator PDF is Here.

All of the code, the use case and a cheat sheet for the video can be found after the video below. You should refer to it through out this video to help you learn the topics covered.
